Description

Technical Field

[0001] This invention relates to the field of water conservancy pipeline support technology, and in particular to an adjustable support structure for water conservancy pipeline installation in water conservancy projects. Background Technology

[0002] my country has a vast territory and complex terrain. The development of many places is constrained by water. In an era where the freshwater crisis is becoming increasingly apparent, we need to use water rationally and efficiently.

[0003] Because groundwater resources are limited, large-scale development of groundwater can only solve the current crisis but is not sustainable. Therefore, we should make full use of surface water resources. Thus, it is necessary to rationally allocate water resources through artificial transportation. Due to its advantages such as reducing evaporation, facilitating pressurization and pressurization, and high efficiency, pipeline transportation of water resources has become the primary choice for water conservancy transportation.

[0004] In existing water conservancy pipelines, once the support components are fixed, they cannot be adjusted. Due to the limited installation position of the support components, it is impossible to achieve multi-angle adjustments to maximize the adaptation to the access direction of the water conservancy pipeline. This results in the pipe components being subjected to additional bending forces, affecting the reliability of the connection between the pipe components. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides an adjustable support structure for the installation of water conservancy pipelines in water conservancy projects.

[0016] like Figure 1-11 As shown, an adjustable support structure for water conservancy pipeline installation in a water conservancy project includes a base 1, a first support frame 8 on the base 1, a first support member 2 on the upper end of the first support frame 8, a lateral adjustment structure on the base 1, a second support frame 10 driven and connected to the lateral adjustment structure, a second support member 7 corresponding to the first support member 2 on the second support frame 10, and a tilting structure on the base 1 that cooperates with the lateral adjustment structure. The tilting structure is driven and connected to the second support member 7, and a positioning structure that cooperates with the tilting structure is provided on the second support member 7. The positioning structure includes a pair of opposing movable limiting plates 51, and a plurality of scraper blocks 52 are evenly arranged on the limiting plates 51.

[0017] In use, the pipe to be connected is placed on the first support member 2. The first support frame 8 supports and fixes the first support member 2. The connection direction is adjusted according to the position of the pipe, and the lateral adjustment structure is controlled to work. The second support frame 10 rotates in parallel, thereby adjusting the orientation of the second support member 7 on the second support frame 10, which facilitates the adjustment of the planar connection direction of the pipe. Depending on whether the pipe is assembled at an angle, the tilting structure can be controlled to work, thereby adjusting the tilt direction of the second support member 7. This allows for multi-angle adjustments to maximize the adaptation to the connection direction of the water conservancy pipe, effectively avoiding the pipe being subjected to additional bending forces, which would affect the reliability of the connection between pipes. After adjusting the orientation of the second support member 7 according to the actual connection situation of the pipe, the connection pipe is placed on the second support member 7. When the second support member 7 tilts, the positioning structure works, and the limiting plate 51 moves towards each other. The scraper 52 at one end of the limiting plate limits and fixes the position of the connection pipe, preventing the connection pipe from sliding down when the second support member 7 tilts, which would affect the installation of the pipe.

[0018] The lateral adjustment structure includes a handle 4 rotatably connected to the base 1. One end of the handle 4 is fixedly connected to a worm gear 15. The worm gear 15 meshes with a worm wheel 16. The worm wheel 16 is coaxially fixedly connected to a small gear 5. The small gear 5 meshes with a large gear 6 rotatably connected to the base 1. One end of the large gear 6 is fixedly connected to a second support cylinder 13. The second support frame 10 is provided on the second support cylinder 13.

[0019] like Figure 1 and 2 As shown in Figure 11, when the angle of the access pipe on the second support member 7 is adjusted in a plane, the handle 4 is rotated, the handle 4 drives the worm gear 15 to rotate, the worm gear 15 drives the worm wheel 16 to rotate, the worm wheel 16 drives the pinion 5 to rotate, the pinion 5 drives the large gear 6 to rotate. Since the large gear 6 has a second support cylinder 13 at one end, the large gear 6 rotates and drives the second support cylinder 13 to deflect circumferentially. The second support cylinder 13 drives the second support frame 10 to deflect circumferentially, thereby adjusting the orientation of the second support member 7 on the second support frame 10.

[0020] The second support frame 10 has a connecting plate 11 at its upper end. One end of the connecting plate 11 is fixedly connected to a fixed support column 32, and the second support member 7 is rotatably connected to the fixed support column 32.

[0021] like Figure 7 As shown, the connecting plate 11 supports and fixes the fixed column 32, and the fixed column 32 acts as a bearing for the second support member 7 to rotate.

[0022] The tilting structure also includes a motor 9 fixedly connected to the base 1. The front end of the motor 9 is provided with a first support cylinder fixedly connected to the base 1. The output end of the motor 9 is fixedly connected to a first rotating ring 17 rotatably connected to the inner wall of the first support cylinder. A plurality of first rotating columns 18 are evenly arranged on the first rotating ring 17. A second rotating ring 21 is rotatably connected to the inner wall of the second support cylinder 13. A plurality of second rotating columns 20 corresponding to the first rotating columns 18 are evenly arranged on the second rotating ring 21. A universal joint 19 is provided between the first rotating columns 18 and the second rotating columns 20. One end of the second rotating ring 21 is fixedly connected to a driving cone. Gear 22, the driving bevel gear 22 meshes with the driven bevel gear 23, the driven bevel gear 23 is fixedly connected to the rotating rod 24, the rotating rod 24 is fixedly connected to the grooved wheel 25, one end of the connecting plate 11 is fixedly connected to the second support plate 26, the inner wall of the second support plate 26 is slidably connected to the first slide rod 27, the upper end of the first slide rod 27 is respectively provided with the fixed rod 28 on both sides, one end of the fixed rod 28 is fixedly connected to the fixed plate 29, the inner side of the fixed plate 29 is provided with the pin 30 slidably connected to the inner wall of the second support member 7, and the lower end of the first slide rod 27 is provided with the first sliding pin 31 corresponding to the grooved wheel 25.

[0023] like Figure 3 and 4As shown in Figure 5, when motor 9 operates, its output drives the first rotating ring 17 to rotate under the limit of the first support cylinder. Simultaneously, the first rotating ring 17 drives the first rotating column 18 to rotate. The first rotating column 18 drives the second rotating column 20 to rotate via a universal joint 19. The second rotating column 20 drives the second rotating ring 21 to rotate under the limit of the second support cylinder 13. The universal joint 19 is located at the center of the large gear 6. Therefore, when the second support cylinder 13 rotates circumferentially with the large gear 6, the rotation of the first rotating column 18 and the second rotating column 20 is unrestricted. Furthermore, since one end of the universal joint 19 of the second rotating column 20 always rotates around the center of the large gear 6, the first rotating column 18 is unrestricted when rotating circumferentially with the first support cylinder. This effectively ensures that the second support member 7 can be obliquely deflected according to the connection direction after rotating to a certain angle, improving the multi-angle capability of the connection direction and effectively avoiding additional bending after pipe connection. When the second rotating ring 21 rotates, it drives the active bevel gear 22 to rotate, which in turn drives the driven bevel gear 23 to rotate. The driven bevel gear 23 then drives the rotating rod 24 to rotate. One end of the second support cylinder 13 is provided with a first support plate 14, which supports the rotating rod 24. When the rotating rod 24 rotates, it drives the grooved wheel 25 to rotate. During the rotation, the grooved wheel 25 engages with the first sliding pin 31 at the lower end of the first sliding rod 27, thereby driving the first sliding rod 27 to slide up and down along the inner wall of the second support plate 26. When the first sliding rod 27 moves upward, it drives the fixed plate 29 to move upward through the fixed rod 28. The fixed plate 29 then drives the pin 30 to move upward. Since the pin 30 and the inner wall of the second support member 7 are slidably connected, and one end of the second support member 7 is rotatably connected to the fixed support column 32, by controlling the upward movement of the first sliding rod 27, the second support member 7 can be driven to deflect upward, thereby adjusting the inclination direction of the pipe connection on the second support member 7.

[0024] The positioning structure also includes a fixed bevel gear 33 fixedly connected to the fixed support column 32. One end of the second support member 7 is provided with a frame plate, on which a rotating bevel gear 34 meshes with the fixed bevel gear 33. The rotating bevel gear 34 is coaxially fixedly connected to a first sprocket 38. The first sprocket 38 is connected to a second sprocket 35 via a chain belt 37. A turntable 36 is provided inside the second sprocket 35. A second sliding pin 46 is provided at a non-center position on the turntable 36. Opposite to the second sliding pin 46, a feature is provided on the surface of the turntable 36. The corresponding grooved rod 47 has a connecting rod 45 fixedly connected to one end, and a spur rack 40 is provided at the lower end of the connecting rod 45. A limiting frame 39 that is slidably connected to the spur rack 40 is fixedly connected to the second support member 7. The spur rack 40 meshes with a spur gear 41 that is rotatably connected to the second support member 7. A central connecting rod 42 is fixedly connected to the spur gear 41 on the same axis. Side connecting rods 43 are rotatably connected to both ends of the central connecting rod 42. A second sliding rod 44 that is slidably connected to the inner wall of the second support member 7 is fixedly connected to one end of the side connecting rod 43.

[0025] like Figure 6-9 As shown, since the second support member 7 rotates around a fixed support shaft, when the second support member 7 rotates, the rotating bevel gear 34 on one side of the second support member 7 meshes with the fixed bevel gear 33 on the fixed support shaft. The rotating bevel gear 34 rotates, driving the first sprocket 38 to rotate. The first sprocket 38 then drives the second sprocket 35 to rotate via the chain belt 37. The second sprocket 35 drives the turntable 36 to rotate. During the rotation of the turntable 36, the second sliding pin 46 rotates circumferentially. During the circumferential rotation of the second sliding pin 46, the grooved rod 47 slides along the upper surface of the turntable 36. Since one end of the grooved rod 47 is provided with... The connecting rod 45 and the spur rack 40 at the lower end of the connecting rod 45 are restricted by the limiting frame 39. Therefore, the groove rod 47 drives the connecting rod 45 to slide along the axial direction of the limiting frame 39. During the movement of the connecting rod 45 and the spur rack 40, they mesh with the spur gear 41, thereby driving the spur gear 41 to rotate. Since the spur gear 41 and the middle connecting rod 42 are fixedly connected at the middle position, the rotation of the spur gear 41 can drive the middle connecting rod 42 to rotate about the midpoint as the axis. During the rotation of the middle connecting rod 42, it drives the side connecting rods 43 at both ends to deflect in opposite directions. During the deflection of the side connecting rods 43, it drives the second sliding rod 44 to slide along the inner wall of the second support member 7.

[0026] The upper end of the second slide bar 44 is fixedly connected to a shaft block 48, and an insert rod 50 is slidably connected to the inner wall of the shaft block 48. One end of the insert rod 50 is fixedly connected to the limiting plate 51, and a spring 49 is provided between the limiting plate 51 and the shaft block 48 and sleeved and connected to the insert rod 50.

[0027] like Figure 8 and 9 As shown in Figure 10, during the sliding process of the second slide rod 44, it drives the shaft blocks 48 to slide towards each other. During the movement of the shaft blocks 48, they respectively drive the limiting plate 51 to move in the center. The scraper block 52 at one end of the limiting plate 51 is used to limit and fix the access pipe on the second support member 7, so as to prevent the access pipe from sliding down with the deflection of the second support member 7 and affecting the connection of the pipe. A spring 49 is set between the shaft block 48 and the limiting plate 51. When the limiting plate 51 is compressed, the insertion rod 50 can slide along the inner wall of the shaft block 48 and the spring 49 is compressed. It can be used to limit and fix pipes of different diameters and has good applicability.

[0028] Limiting plates 3 are respectively provided on both sides of the upper end of the first support member 2.

[0029] like Figure 1 As shown, the limiting plate 3 is used to limit the position of the pipe on the first support member 2.

[0030] The working process of this invention is as follows: When using this invention, the pipe to be connected is placed on the first support member 2. The first support frame 8 supports and fixes the first support member 2. The connection direction is adjusted according to the position of the pipe. The handle 4 is rotated, which drives the worm gear 15 to rotate. The worm gear 15 drives the worm wheel 16 to rotate. The worm wheel 16 drives the pinion 5 to rotate. The pinion 5 drives the large gear 6 to rotate. Since the large gear 6 has a second support cylinder 13 at one end, the rotation of the large gear 6 drives the second support cylinder 13 to deflect circumferentially. The second support cylinder 13 drives the second support frame 10 to deflect circumferentially, thereby adjusting the orientation of the second support member 7 on the second support frame 10, which facilitates the adjustment of the plane connection direction of the pipe.

[0031] Depending on whether the pipeline is assembled at an angle, motor 9 operates. The output end of motor 9 drives the first rotating ring 17 to rotate under the limit of the first support cylinder. The first rotating ring 17 simultaneously drives the first rotating column 18 to rotate. The first rotating column 18 drives the second rotating column 20 to rotate through the universal joint 19. The second rotating column 20 drives the second rotating ring 21 to rotate under the limit of the second support cylinder 13. The universal joint 19 is located at the center of the large gear 6. Therefore, when the second support cylinder 13 rotates circumferentially with the large gear 6, the rotation of the first rotating column 18 and the second rotating column 20 is not restricted. When the second rotating ring 21 rotates, it drives the driving bevel gear 22 to rotate. The driving bevel gear 22 drives the driven bevel gear 23 to rotate. The driven bevel gear 23 drives the rotating rod 24 to rotate. One end of the second support cylinder 13 is provided with a first support plate 14. The first support plate 14 supports the rotating rod 24. 4. It plays a supporting role. When the rotating rod 24 rotates, it drives the grooved wheel 25 to rotate. During the rotation, the grooved wheel 25 engages with the first sliding pin 31 at the lower end of the first sliding rod 27, thereby driving the first sliding rod 27 to slide up and down along the inner wall of the second support plate 26. When the first sliding rod 27 moves upward, it drives the fixed plate 29 to move upward through the fixed rod 28. The fixed plate 29 drives the pin 30 to move upward. Since the pin 30 and the inner wall of the second support member 7 are slidably connected, and one end of the second support member 7 is rotatably connected to the fixed column 32, by controlling the first sliding rod 27 to move upward, the second support member 7 can be driven to deflect upward, thereby adjusting the inclination direction of the pipe connection on the second support member 7. This allows for multi-angle adjustment to maximize the adaptation to the connection direction of the water conservancy pipeline, effectively avoiding the pipeline from being subjected to additional bending force, which would affect the reliability of the connection between pipelines.

[0032] The access pipe is placed on the second support member 7. When the second support member 7 tilts, since the second support member 7 rotates around the fixed support shaft, the rotating bevel gear 34 on one side of the second support member 7 meshes with the fixed bevel gear 33 on the fixed support shaft. The rotating bevel gear 34 rotates, driving the first sprocket 38 to rotate. The first sprocket 38 then drives the second sprocket 35 to rotate via the chain belt 37. The second sprocket 35 drives the turntable 36 to rotate. During the rotation of the turntable 36, the second sliding pin 46 rotates circumferentially. During the circumferential rotation of the second sliding pin 46, the grooved rod 47 slides along the upper surface of the turntable 36. Since a connecting rod 45 is provided at one end of the grooved rod 47, and the spur rack 40 at the lower end of the connecting rod 45 is restricted by the limit frame 39, the grooved rod 47 drives the connecting rod 45 to slide axially along the limit frame 39. During the movement of the spur rack 40 driven by the connecting rod 45, it meshes with the spur gear 41. The spur gear 41 is driven to rotate. Since the spur gear 41 and the connecting rod 42 are fixedly connected at the middle, the rotation of the spur gear 41 can drive the connecting rod 42 to rotate around its midpoint. During the rotation of the connecting rod 42, the side connecting rods 43 at both ends are deflected in opposite directions. During the deflection of the side connecting rods 43, the second sliding rod 44 is driven to slide along the inner wall of the second support member 7. During the sliding of the second sliding rod 44, the shaft block 48 is driven to slide in opposite directions. During the movement of the shaft block 48, the limiting plate 51 is driven to move in the center. The scraper 52 at one end of the limiting plate 51 is used to limit and fix the access pipe on the second support member 7, so as to prevent the access pipe from sliding down with the deflection of the second support member 7 and affecting the connection of the pipe. A spring 49 is set between the shaft block 48 and the limiting plate 51. When the limiting plate 51 is compressed, the insertion rod 50 can slide along the inner wall of the shaft block 48 and the spring 49 is compressed. It can be used to limit and fix pipes of different diameters and has good applicability.
